Most people with a degree in CS know what Big O stands for. It helps us to measure how well an algorithm scales. How do you calculate or approximate the complexity of your algorithms?

76 After a lot of Googling, I've found that most sources say that the Dijkstra algorithm is "more efficient" than the Bellman-Ford algorithm. But under what circumstances is the Bellman-Ford algorithm better …

While solving a geometry problem, I came across an approach called Sliding Window Algorithm. Couldn't really find any study material/details on it. What is the algorithm about?

Sep 23, 2016 · The algorithm maintains the index to put the pivot in variable i and each time it finds an element less than or equal to pivot, this index is incremented and that element would be placed …

Oct 23, 2012 · A* is just like Dijkstra, the only difference is that A* tries to look for a better path by using a heuristic function which gives priority to nodes that are supposed to be better than others while …

Feb 25, 2010 · An algorithm is the description of an automated solution to a problem. What the algorithm does is precisely defined. The solution could or could not be the best possible one but you know from …

At each iteration the algorithm chooses a node to expand from the open set (the one with the lowest f function - the f function is the sum of the cost the algorithm already knows it takes to get to the node …

4 days ago · 5 replies 33 views Algorithm for selecting random representative subset based on absolute frequencies Given a long list of (unique) names, as well as an absolute frequency for each name, …

Dec 1, 2023 · This is a simple question from algorithms theory. The difference between them is that in one case you count number of nodes and in other number of edges on the shortest path between …

Feb 22, 2010 · A common algorithm with O (log n) time complexity is Binary Search whose recursive relation is T (n/2) + O (1) i.e. at every subsequent level of the tree you divide problem into half and do …
